[cairo] About YUV2RGB converstion

[conner.mo]

Dear all,  
 
Currently we only have RGB support in cario and glitz. Therefore, if we want to put videos on a cairo surface in 
YUV format, a software colorspace conversion has to be taken. As you can imagine, the performance is 
horrible. I wonder if it is possible to add a hardware accelerated conversion function in the glitz layer so that 
cairo can benefit from that. Thanks.
